Navigation shoes indoor navigation correction method and device

Abstract

The invention provides a navigation shoes indoor navigation correction method. One or more fixed points are included indoors and have corresponding fixed magnetic field information and fixed position information; the fixed points, the corresponding fixed magnetic field information and the corresponding fixed position information are stored in a server side; navigation shoes include current course information and current position information. The method comprises when one of the fixed points is reached, the navigation shoes receive the fixed point-corresponding fixed magnetic field information and fixed position information; the fixed magnetic field information and the fixed position information are received by a mobile terminal from the server side and are sent to the navigation shoes; the navigation shoes adopt the fixed magnetic field information to correct the current course information; and the navigation shoes adopt the fixed position information to correct the current position information. The method is used for ensuring the indoor navigation accuracy of the navigation shoes.

Description

technical field [0001] The invention relates to the technical field of indoor positioning, in particular to a method for correcting indoor navigation of navigation shoes, and a device for correcting indoor navigation of navigation shoes. Background technique [0002] With the development of science and technology, in order to meet people's various navigation needs, more and more navigation systems are used for positioning needs in different occasions. [0003] In existing pedestrian navigation devices, receivers of satellite navigation systems, such as GPS (Global Position System, Global Positioning System) receivers, are usually used, and such devices need to receive navigation information from multiple satellites. However, GPS equipment cannot perform positioning anywhere, for example, it cannot locate indoors or places with high interference, because GPS equipment cannot receive satellite signals in indoor environments. At present, low-cost pedestrian navigation equipmen...

AI Technical Summary

Problems solved by technology

However, GPS equipment cannot perform positioning anywhere, such as indoors and places with high interference, because GPS equipment cannot receive satellite signals in indoor environments

At present, low-cost pedestrian navigation equipment based on MEMS inertial devices is an effective solution for navigation problems, but MEMS inertial devices have low precision, large measurement errors, and position and attitude calculations are iterative calculations, so errors will accumulate quickly and cannot be carried out. Effective positioning for a long time cannot meet the requirements of precise navigation

As for other indoor navigation systems, such as indoor navigation using wifi (Wireless Fidelity, wireless local area network) or cameras, it will be affected by the complex indoor environment, and the cost is high
